Are you using Google Apps? Ready to upgrade to a single-sign-on for your various Google services, but the options hasn’t become available yet? It’s probably not shown up because you made an account for your Apps email outside of Apps. Yeah – it’s really confusing. Hopefully merging them will help. So here’s how!

Not all of your accounts will migrate, for example if you have an account info@example.com and that was used to create AdSense, AdWords (and others) they will block the migration of info@example.com until Google patches their system. Other accounts will migrate properly.
